Aikido has little to nothing in common with type of fighting done in MMA. This is not to say that one is better than the other, it's simply to say that they are VERY different. MMA is concerned with one-on-on fighting, done in a controlled atmosphere, with a referee, unarmed, playing by a ruleset. Aikido is concerned with conflict resolution, against multiple attackers, likely armed, in less than ideal settings, at unexpected times. Different.
